1 监听对象时
watch: {
spobj: {
handler: function (val, neval) {
this.initChart(this.line)
},
deep: true// 对象内部的属性监听，也叫深度监听
}
},
2 监听数组
watch: {
statdata (nnn, ooo) {
let that = this
let num1 = ((that.statdata[0]) / (that.sum != null ? that.sum : 1) * 100).toFixed(2)
let num2 = ((that.statdata[1]) / (that.sum != null ? that.sum : 1) * 100).toFixed(2)
let num3 = ((that.statdata[2]) / (that.sum != null ? that.sum : 1) * 100).toFixed(2)
let first = that.statdata[0] === undefined ? 0 : ((num1 > 0) ? num1 : 0)
let seconde = that.statdata[1] === undefined ? 0 : ((num2 > 0) ? num2 : 0)
let third = that.statdata[2] === undefined ? 0 : ((num3 > 0) ? num3 : 0)
let forth = that.sum != 1 && that.sum != null ? ((100 - first - seconde - third).toFixed(2) > 0 ? (100 - first - seconde - third).toFixed(2) : 0) : 0
this.initChart(first, seconde, third, forth)
}
// 是一个复合数组，每个元素是个对象
arra(nnn, ooo) {
this.efmobj.factoryname = this.arra.length != 0 ? this.arra[0].factoryID : null
this.getlinedata(this.efmobj.factoryname)
},
